Which combination of actions should a database specialist take to meet these requirements?
(Choose three.)
Establish an AWS Direct Connect hosted connection between the company’s data center and AWS.
Create an AWS Site-to-Site VPN connection between the company’s data center and AWS over the internet.
Use AWS Database Migration Service (AWS DMS) to migrate the on-premises SQL Server databases to Amazon RDS for SQL Server. Configure Always On availability groups for SQL Server.
Deploy a new SQL Server Always On availability group DB cluster on Amazon EC2. Configure Always On distributed availability groups between the on-premises DB cluster and the AWS DB cluster. Fail over to the AWS DB cluster when it is time to migrate.
Grant system-level access to the third-party backup product to perform backups of the Amazon RDS for SQL Server DB instance.
Configure the third-party backup product to perform backups of the DB cluster on Amazon EC2.
Explanations:
AWS Direct Connect provides a high-bandwidth, low-latency connection, supporting a 2 Gbps requirement for Always On asynchronous replication, ensuring stable data transfer between the on-premises setup and AWS.
AWS Site-to-Site VPN does not guarantee the 2 Gbps bandwidth required for replication and may experience latency over the internet, which is unsuitable for high-performance replication needs.
AWS DMS is not suitable for continuous real-time synchronization for a high-performance Always On availability group. AWS DMS typically performs batch migrations and would not support the required low-downtime migration.
Deploying SQL Server Always On in Amazon EC2 enables the use of distributed availability groups, which allow asynchronous replication to AWS and meet the requirement for high-performance with minimal downtime during migration.
Amazon RDS for SQL Server does not allow system-level access required by the third-party backup product, making it unsuitable for this use case.
The third-party backup product can be configured to access the SQL Server on Amazon EC2, as this setup allows system-level access necessary for backups, meeting the company’s requirements.
